Lrrl Ia IS · 904 · lt81 Indian Standard SPECIFICATION FOR 2·WAY AND 3..WAY SUCTION COLLECTING HEADS FOR FIRE FIGHTING PURPOSES ( Second Revision) o. FOREWORD 0.1 This Indian Standard ( Second Revision) was adopted by the Indian Standards Institution on 28 February 1983, after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council. 0.2 2-way and 3-way suction collecting heads are used along with the hoses when supply of water is collected from 2 or 3 sources for fire fighting purposes. This standard was first prepared in 1955 and revised in 1965. A second revision has been prepared in order to give detailed drawings of these items besides making its contents in line with similar latest Indian Standards. 0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated. expressing the result of a test, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified vaJue in this standard. and dimensions, construction, workmanship and finish and ~rfornlance tests of 2-way and 3-way suction colJecting heads. 1.
